Disable/Enable Internal Cache on 486 CPUs

Filename: CACHEOFF.COM / CACHEON.COM
Summary:  Modern BIOSes normally enable the CPU cache automatically. Some programs need it off.

Some BIOSes will allow the internal CPU cache to be enabled or disabled. Most modern BIOSes, including Phoenix 4.xx, will automatically enable the internal CPU cache and there is not normally an option in CMOS setup to disable it as there is normally no need to do so. There may be some older DOS programs that need the cache disabled. 

These programs are not BIOS specific, so they should work with any system with a 486 processor. The only caveat is that certain programs may re-enable the 486 cache; the main group of programs that are likely to do this is programs that use a DOS extender.

CACHEON.COM and CACHEOFF.COM Are part of this ZIP file. After turning cache off with CACHEOFF.COM, it should automatically be re-enabled when system is powered off and back on or it can be re-enabled with CACHEON.COM.
